Problem $1.$ Select an I$-$joist for the $9$ sections $($A$,$ B$,$ C$,$ D$,$ E$,$ and four F$\text{'}$s$)$ shown below. Assume a

Live Load $($LL$)$ of $40$ psf and a Dead Load $($DL$)$ of $15$ psf acting on the floor system.

Problem $2.($i$)$ Select a single $2$ ply LVL I$-$Joist that covers the four spans $(12ft.,10ft.,10ft$ and $8ft.)$

as shown below. $($ii$)$ Repeat problem $2($i$)$ and select a $3$ ply LVL I$-$Joist. Assume LVL grade is $2650F_6-$

$1\mathrm{.}9$E$.$ The floor system is subjected to Live Load $($LL$)$ of $400$ plf and a Total Load $($TL$)$ of $500$ plf$.$
